Section 86 Reorganizations: Changing Share Classes for Succession or New Investment — CPA Firm Near You, Montreal

Introduction
When a corporation in Quebec needs to bring in new investors, restructure ownership, or prepare for succession, a Section 86 reorganization is one of the cleanest and most powerful tools available. Section 86 allows shareholders to exchange one class of shares for another on a tax-deferred basis, enabling estate freezes, investor entry, restructuring, or share redesign without triggering immediate capital gains. This guide explains how Section 86 reorganizations work, when to use them, and how a CPA near you in Montreal can help implement them properly.
Legal and Regulatory Framework
Under Section 86 of the Income Tax Act, a shareholder may exchange shares of one class for shares of another class without immediate tax, provided the corporation undergoes a share reorganization that meets the technical requirements. Section 86 is commonly used during estate freezes, recapitalizations, reorganizations of share capital, and introduction of new shareholders. Proper documentation is required, including resolutions, amendments to share structure, updated minute books, share certificates, and corporate filings. CRA requires that the exchange reflect fair market value and commercial intent.
Key Court Decisions
Courts have ruled that improper documentation or share attributes invalidate Section 86 reorganizations. Judges have denied tax-deferral benefits where corporations attempted to manipulate valuations or where corporate records did not support the share exchange. Several decisions confirm that Section 86 cannot be used to manufacture artificial tax losses or circumvent attribution or TOSI rules. Courts emphasize that reorganizations must follow legal requirements and reflect genuine commercial purpose.
Why CRA and Revenu Québec Scrutinize Section 86 Reorganizations
A Section 86 reorganization often involves related-party transactions, new share structures, freeze shares, and growth shares. CRA examines whether share attributes are valid, whether preferred shares match stated values, whether the exchange was proportional and justified, and whether documentation supports the new structure. Revenu Québec reviews minute books, corporate resolutions, valuation reports, and filings for compliance with QBCA or CBCA rules. Mistakes increase audit and reassessment risk.
When to Use a Section 86 Reorganization
Estate freezes
Original common shares are exchanged for fixed-value preferred shares while new common shares are issued to heirs or a trust.
Bringing in new investors
Section 86 allows share redesign without triggering capital gains.
Creating multiple share classes
Used to separate voting and non-voting shares or create dividend flexibility.
Corporate reorganizations
Restructuring ownership or recapitalizing a corporation.
Correcting improper share structures
When original incorporation used only one share class or an inefficient structure.
How Section 86 Works: Step-by-Step
Step 1: Evaluate existing share structure
A CPA reviews existing share classes, voting rights, and legal documents.
Step 2: Establish new share classes
The corporation amends its articles to create preferred or new common shares.
Step 3: Exchange old shares for new ones
Shareholders exchange original shares for new classes on a tax-deferred basis.
Step 4: Update minute books
Resolutions, share certificates, registers, and corporate filings must be updated.
Step 5: Issue additional shares if needed
Growth shares for heirs, investors, or a trust can be issued after the reorganization.
Step 6: Ensure valuation consistency
Preferred shares must reflect fair market value at the time of exchange.
Common Pitfalls
Missing corporate resolutions
Without proper resolutions, CRA may reject the reorganization.
Incorrect share attributes
Preferred shares must include redemption rights and restrictions consistent with tax rules.
Poor valuation
Incorrect values may trigger capital gains or shareholder benefits.
TOSI exposure
New share allocations to family members must comply with income-splitting rules.
Incomplete minute books
Documentation failures create legal and tax vulnerabilities.
